> In flip6, for flink on yarn mode, RM requests container from yarn according to the requirement
of the JM. But the AMRMClientAsync used in yarn doesn't guarantee that the number of containers
returned exactly equal to the number requested. So it need to record the number request by
flink rm and return the redundant ones to yarn.
